Abstract
A new control system for fluorescence and EXAFS studies has been developed consisting of germanium detectors and digital signal processor electronics. Using a standard PC and a new software package leads to a high flexibility regarding application, user interface and use of different synchrotron facilities. The new system achieves spectra with considerably higher quality when compared to a traditional system for fluorescence and EXAFS studies. This allows the investigation of thin films and diluted systems as shown by experiments on a W/Nb multilayer system and on FeS2 doped with Zn.
